' PERLEY R. GLASS, or. wnmnn, MASSACHUSETTS, AssIGNon 'ro UNITED SHOE m CHINERY CORPORATION, OE PATERSON, NEW JERSEY, A CORPORATION oEjNEw 1 JERSEY INKING DEVICE FOR MARKING MACHINES Application filed October 10, 1927, Serial No. 225,211. Renewed May 1, 1930.

This invention relates to marking machines .for use in marking sheet material such as parts of boots and shoes and is illustrated as embodied in a machine of the type shown in Letters Patent of the United States No. 1,172,897, granted February 2, 1916, upon 7 the application of F. W.-Merr1ck.

In marking machinesof {the type under consideration the work is supported in horizontal position upon a platen or work table. The marking is done by means of type wheels or a die carried up and down upon an oscillat ing head from "an inoperative position to a position in contact with a iece of work on. the platen. Ink is applie to the marking device between the oscillations of the mark ing head, usually by means of a pad which is oscillated from an inoperative position to a position underlapping. the marking device when the latter is. in its elevated position. Such an arrangement has proved to be satis' factory when the marking devices used are of small dimensions,'such as a row of type or the like, but, when it is desired to use the" machine for marking large designs upon shoe uppers to guide in the application of fancy stitching thereon, difliculty has been experienced because of the unusually wide pad needed to apply ink to the whole surface of the large marking die.

Accordingly, an object of the present invention is to provide an improved arrangement for applying ink to a marking device by which the inking of dies of large dimensions may be facilitated. In the illustrated arrangement, in accordance with features of the invention, the inkingpad is swung upwardly and slid outwardly into operative po- L sition so that said pad is brought to a posi tion fully underlapping a markigig device even of large size. With this arrangement there is no interference with other parts of the machine when the pad is manipulated,

either as it moves back to inoperative position or when it is moved out of operative or inking position.

For best results the inking pad must be applied to the die firmly and evenly without any slurring thereof, and another feature ofthe invention resides in an organization by means of which the sliding movement of the pad is completed prior to the contact of the pad with the die, thus pressing the pad evenly against the die by means of a simple swinging movement of the pad carrier.

In the drawings,

Fig. 1 is a side elevationof a chine to which my improved inkin 'pad has been applied, showing the pad in in ing position, and

Fig. 2 is a similar view of the parts, shown in outline, in the position in which the mark- 1 tive position.

The machine illustrated comprises a frame made up of side members 10 and 12 between ng pad'has been moved back to inopera- '-which are mounted a drive-shaft 14 and a ififiidevice is in contact with the work and the I marking ma:

At the outer end of the walkcarrying at its lower end a marking device 22 in the form of a flatdie of substantial, dimensions, as large as the palm of the hand, for

example. The upright member 20 is supported for movement-in parallel, substantially vertical planes by means of a link 24 interposed between the frame and said upright member.

' Pieces ofwork are supported upon a work table or platen 30 carried at the outer end of an arm 32 which is secured to the side frames 10 and 12, and the platen 30 is arranged for control automatically to adjust it-.

self to varying thicknesses of work by means ofan arm'34 and other parts more fully illustrated and described in the patent to Merrick to which reference has been made above. The machine is provided with a suitable clutch controlled through a treadle rod 36 and may be caused to go through a single cycle of movement or successive cycles at the will of the operator.

Because of the considerable breadth of the marking device 22, a ,pad 'sugiiciently wide to apply ink to the whole of said die, mount-.

ed for simple swinging movement, as in the machine of the Merrick patent, would intercordingly,

fere with other parts of the machine.- Acinthe illustrated attachment, which may be substituted for the inking de vice of'a machine of the Merrick patent, the inking pad 40 is slidingly mounted, by means are dovetail connection, upon a flat plate 42 carried at the outer end ofa swinging arm 44, thereby providing an arrangement for, in effect, extending the length of said arm when moving the pad to inking position and shortening it when the marking head descends to avoid interference between the pad and the work-support.- The inner end 'of this arm is pivoted at 46 between .the side frames 10 and 12, and the arm is swung in and out through a series of positions occupying definitely related intersecting planes, by reason of its connection to the upright member 20 through a link 48.

' This link 48 is pivotally attached at its lower end to the arm 44 and at its upper end to a stud 5O havingintegral eccentric pivots thereon mounted in a projecting member 52 which is integral with the upright member 20. By adjusting thisstud 50, the contact pressure between the pad and the die 22 may be controlled. The inking pad 40, besides being swung outward by the arm 44, is also controlled by means of links 54,56 and 58 which are interconnected at arranged to alter their adjacent ends and are the relation of the pad 40 and the arm it wholly to underlap the face of the marking die. In so doing it is moved into contact with the marking die to provide ink therefor pr1or to the next succeeding marking operation. It

imparting a sliding movement to the inking pad 40 along the swinging arm 44.- To this end the outer end of the link 54 is pivotally connected to the under side of the inking pad pt 60 and the innerend of the link 58 is loosey pivoted upon the drive shaft 14. A fulcrum 62 .for an intermediate part of the middle link 56 isprovided by means of a depending finger 64 upon the swinging arm44: Itis to be understood that no power is imparted to links 54, 56 and 58 from the drive shaft 14 and that the sliding'of the inking pad 40 with will be seen that the relation of the links controlling'the slidin movement of the ink pad 40 (and specifica ly the horizontal relation of the fulcrum 62 and the pivotal connection between the links 54'and 56) is such that the sliding movement of said pad has been completed before the pad is brought into contact with the marking. die 22, thus avoiding an poi' tions of the marking die and giving to the pad a simple movement of impression against themarkin die.

Having t us described by invention, what I claim as new and desireto secure by Let v ters Patent of the United States is:

1. In a marking machine having a marking device and a platen which are relatively movable to-bring the marking device into contactwith a piece of work supported on the platen a pad for applying1 ink to the marking device, a support for sai pad, and means for'sliding said pad on the support and at the same time swinging the support to bring the padinto contact with the marking device when the latter is separated from the platen. a

2. In a marking machine having a mark-. ing device and a platen which are relatively movable to bring the marking device into contact with'a piece of work' supported on the platen, a pad for applying ink to the relation-to the swinging arm 44 results soleily from the swinging movement of the pa with'respect to the fixed fulcrum provided by the drive shaft 14. As a I result, when the marking device 22 starts to move down into marking position-the swinging arm 44 is turned on its pivot 46 and at the same time the.inking pad 40 is moved in:

wardly along the upper face of the rigid carrying plate 42, thus shortening the'distance between the outer endof the pad and the pivot 46. -This movement will carry the pad to I the position shown in Fig. 2 where it is out of theway of the marking die 22 as the Y latter is applied to a piece of work 70 supported upon the platen 30 and interference betweenthe inking pad and other parts of the machine, specifically the platen/ 30, has been avoided. When the marking die moves up to its inoperative position shown in Fig. 1, the inking pad is again swung upwardly and is slid forward along the arm 44 to cause marking device, a swinging support constructed and arranged to carry said pad from a position out of the range of relative'movement of said marking device and platen .into a position in contact with the marking device, and means for sliding said pad on said swinging support to reduce the space required for said swinging movement.
